WILLIAM PERCY SIMPSON, OF OVERBROOK, PENNSYLVANIA.

COMBINATION POWER LAWN MOWER AND ROLLER.

SPECIFICATION forming part of Letters PatentNo. 670,458, dated March 26,1901.

Application filed June 1, 1900- v To all whom it may concern:

Be it known that I, WILLIAM PERCY SIMP- soN, a citizen of the UnitedStates, residing at Overbrook, in the county of Montgomery and State ofPennsylvania, have invented certain new and useful Improvements in Combination Power Lawn Mowers and Rollers, of which the following is aspecification.

My invention relates to apparatus for mowing and rolling lawns; and itconsists in a combined cutter and roller constructed so as to secure arapid cutting .and rolling operation, as fully set forth hereinafter andas illustrated in the accompanying drawings, in Which Figure l is a sideelevation of my improved combination of mower and roller, and Fig. 2 aplan view. 7

The frame of the apparatus is of any suitable construction to supportthe operating parts and for connection with the mowing and rollingdevices.

As shown, the frame A is supported at the rear by a roller B and at thefront by the frame 0 of the combined roller and mower. The cutting ormowing device may be a rotating head D, with knives cutting againstablade 6, as shown, or may consist of reciprocating knives, as sometimesemployed, and the roller E is at the rear of the cutter and supports theframe 0 at the rear, while the front portion of the frame 0 is supportedby a series of rollers F. Suitable means, as-

sprockets 3 and 1 and a chain 5, are employed for imparting motion tothe cutting devices from the shaft of the roller E. The frame 0 ispivoted to the frame A and is adapted to swing under it, and the pintleor shaft 7 of the frame 0 extends upward through the frame A and isprovided with an arm 8, carrying a swinging nut 9, into which extends along screw-shaft 10, having a handle 11 adjacent to a seat 12 at therear of the machine, so that the operator on said seat by turning saidhandle may turn the frame 0, thus properly directing the course of themachine, so as to out upon any path required.

The frame A may be driven by horse-power or otherwise, as desired; but,as shown, it carries a motor G and a boiler H above the Serial No.18,754.. (No model.)

above described I combine the cutter and V roller in such manner thatthe rolling is effected in the line of the cut and that the two aredirected simultaneously, being mounted in the same frame, so as toproperly cooperate. At the same time in addition I secure the advantageof a heavier roller B, supporting the weight of the machine andoperator, so that the grass may be rapidly cut and maintained in a mostefiective condition, while by the use of a motor upon the frame I amenabled to operate more rapidly and with less injury to the sod thanresults when the apparatus is propelled by an animal.

Without limiting myself to the precise details of construction andarrangement of parts shown, I claim as my invention- In a lawn mower androller, the combination of a frame A, a motor supported on the frame, aroller journaled in the frame near the rear end thereof, gearing totransmit motion to said roller fromthe motor, a frame 0 having aVertical pintle journaled in the front end of the frame A, a roller Ejournaled in the frame C, a rotary cutter journaled in the frame 0 inadvance of the roller E, means to transmit movement from the roller E tothe cutter, and devices connected to the frame 0 and extending above theframe A for swinging the frame 0 and its roller and cutter,substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WM. PERCY SIMPSON. v
